Pure and lanthanum doped barium titanate (BT) ceramics were prepared by sintering pellets at 1300°C for 8h, obtained from nanopowders synthesized by the polymeric precursor method. XRD results showed formation of a tetragonal structure. The presence of dopants changed the tetragonal structure to pseudo-cubic. The polygonal grain size was reduced up to 300nm with addition of lanthanum as a donor dopant...
